Ecological validity should be the cornerstone of any assessment of cognitive functioning. For this purpose, we have developed a preliminary study to test the Art Gallery Test (AGT) as an alternative to traditional neuropsychological testing. The AGT involves three visual search subtests displayed in a virtual reality (VR) art gallery, designed to a...
Conference Paper
Alcohol dependence syndrome has been associated to disfunctions of the pre-frontal cortex, with a negative impact on several areas of cognitive functioning, such as attention, memory and learning, visual-spatial synthesis, executive functions, and psychomotor functions. These changes in turn contribute to the perpetuation of the addictive behavior....

Currently there are several neuropsychological computerized assessment instruments. However, despite the fact that the Toulouse-Piéron cancellation test (TP) is one of the most-used tools to assess attention, it can only be applied in an analog format. In addition, the TP does not assess how the visual tracking is performed during application. The...
